The friction in Lutz's family caused by his choice of profession comes to a head, and he runs away from home to get away from it all.
I know how hard you've worked!
I know how much you've sacrificed!
!أعلم كم بذلت من جهود
!أعلم كم ضحّيت
Ich weiß, wie sehr du dich ins Zeug legst!
¡Sé cuánto te has esforzado!
¡Lo mucho que has sacrificado!
Sé cuánto te has esforzado.
Lo mucho que has sacrificado.
Je sais à quel point
tu travailles dur
Io lo so che hai sempre lavorato duro, Lutz!
Eu sei o quanto você se esforçou!
Sei de tudo pelo que você passou!
Я видела, как ты старался 
и во многом себе отказывал!
